  1. @timbray we have scalable and viable capture and storage technology; it's called "trees". We need to be preserving the ones we have and planting a lot more. #afforestation #reforestation

    A Journal of #Environmental Sciences study investigates #trees best suited for #cities
    Researchers identify tree species with high #carbonSequestration potential and low air pollutant emissions for smarter #afforestation strategies

  3. Forests can't be used in NDC (nationally determined contribution).Forests are in adaptation mode, that is, death by drought, bugs, fires, until new ecosystem members have moved in long after °C is stabilized.
    Trees adapt to longer growth seasons, higher temperatures, over-fertilisation by CO2. This means less water and nutrients and makes them unhealthy.

    Trees only park our CO2, then they burn.

    #Koutsodendris et al 2020 counted pollen at Lake Ohrid, Albania.
    Look at the gap between rising °C 🟡 vs rising pollen count for temperate/mesophilus trees 🟤 🟢.

    Adapting to a new climate takes time, even with seed-carriers and migration corridors: 1000yrs until new ecosystem members have moved in and adaptation to a new stable climate is accomplished.

    But we don't have migration corridors. We have settlements and agricultural wastelands with pesticides everywhere.

    Also, sinks start outgassing once ppm drops. So if your #NDC include negative emissions by DACS or CCS to undo a temperature #overshoot, to really remove 1t CO2 from the system, you must remove 1.5t once we're in the negative emissions phase.

    Outgassing is a physical process to balance changes in atmosphere composition. But of course, when ppm drops considerably, it also changes °C and regional climate and hydrological cycles – again. So your ecosystem is going into adaptation mode all over again. Forests burn.. again.

    Overshoot scenarios aren't a good idea, even if we had working technology and concepts. CO2 removal adds another stressful phase and prolongs adaptation to changing factors – for us and our human systems, and for ecosystems on land and in the ocean.

  4. 😎 💦🌳 How can we cool down landscapes? A new study simulates and quantifies various climate adaptation measures such as #afforestation, #agroforestry and #rewetting for the Elbe-Elster district as a model region. zalf.de/en/aktuelles/Pages/FPD

  5. #Ireland: To achieve net zero GHG #emissions, high rates of #afforestation, soil #rewetting, and #cattle destocking are needed. Technical #abatement cannot substitute these actions. #NetZero requires transforming the land sector: doi.org/10.1038/s43247-024-012 #agriculture #landuse

  6. The urgency of implementing large-scale #tree planting is prompting funding of inadequately assessed projects that will most likely have negligible #sequestration benefits and cause potential social & ecological harm: theguardian.com/environment/20 #afforestation #reforestation #landuse

  7. "Global #carbon #emissions from #FossilFuels have risen again in 2023 – reaching record levels, according to new research from the Global Carbon Project science team.

    The annual Global #Carbon Budget projects fossil carbon dioxide ( #CO2) emissions of 36.8 billion tonnes in 2023, up 1.1% from 2022.

    Fossil CO2 emissions are falling in some regions, including #Europe and the #USA, but rising overall – and the scientists say global action to cut fossil fuels is not happening fast enough to prevent dangerous #ClimateChange.

    #Emissions from land-use change (such as #deforestation) are projected to decrease slightly but are still too high to be offset by current levels of #reforestation and #afforestation (new forests).

    The report projects that total global #CO2 #emissions (fossil + land use change) will be 40.9 billion tonnes in 2023.

    This is about the same as 2022 levels, and part of a 10-year “plateau” – far from the steep reduction in emissions that is urgently needed to meet global #climate targets."

  8. #Afforestation & #reforestation may be strategies to mitigate GHG #emissions & #globalwarming. China's "Grain for Green Program" may induce #carbon sinks that offset 1-2% of the extensive #CO2 emissions from all of #China in 2060: doi.org/10.1016/j.resconrec.20 #climatechange #landuse

  9. @alexwild the problem with tree planting is often an extreme overrating of the C sequestration potential - on the one hand if #grasslands are used for #afforestation there is a net loss of #soil C for the first decade(s). On the other there is a high risk for #damage and #disturbance (which is likely to increase in future) during stand development that is not accounted for in the calculations - we should plant trees AND strongly reduce GHG emissions.

  10. "But there’s a lot of #carbon stored in the #forest #soils in #Ireland and we have to be aware of that." To establish storage banks of carbon, these forests have to be kept #intact — as opposed to harvested like spruce — potentially for a very long time, so we don’t disturb the soils. "The less disturbance there is to the forest the less carbon is lost out of the system."
